INTEGRATED SERVICES
Our services revolve around our core objectives to provide quality products with unparalleled technical support and precise analysis while leading the industry in research and development solutions from an innovative and continuous improvement perspective.
Talented and highly educated team members combine years of experience with state-of-the-art facilities and instrumentation to provide our customers with reference materials and certified reference materials in all ranges required by ISO, UOP, ASTM, API, AGA and GPA while meeting or exceeding the stringent requirements for blending and analysis under ISO 17034 and ISO 17025.
DCG Chemists use industry established analytical techniques to characterize the reference materials and ensure the scientific integrity of the data contained in the Certificates of Concentration of Analytes.
DCG’s highly qualified Team assists customers with the design of Laboratory Quality and Analytical programs to address customers’ needs to meet governmental and industry demand for continuous improvement and stringent guidelines for their products. This includes a guide to ordering reference materials, Proficiency Testing Programs, DCG Interlaboratory Study Programs, Specialized Analytical Services, and DCG’s Advanced School of Chromatography that offers a hands-on learning experience with a practical, “working situation” approach to GC instruction. In addition, DCG offers a full spectrum of custom solutions.

Gain Confidence in Analytical Results
Proficiency Testing ProgramsCONTACT USDCG provides Proficiency Testing Programs (PTPs) to assist customers with objectively quantifying their laboratory’s performance both internally and to other participating laboratories in the industry. To meet the demand for improved analytical results, DCG has designed and implemented a rigorous Analytical Performance Testing Program to verify the analytical performance of client laboratory instruments and on-line analyzers. DCG ships gravimetrically and analytically verified “blind” samples to the customer on a quarterly or semiannually basis for analysis. The Certificate of Concentration of Analytes for all samples and all statistically prepared performance data are provided to the customer’s appointed designee to assure confidentiality. This program will enhance laboratory credibility and ensure optimum quality assurance. Testing programs can be customized to meet the customers quality, regulatory and analytical verification needs.

Evaluate the Quality and Accuracy of results from your laboratory
Interlaboratory and Intralaboratory Study ProgramsCONTACT USDCG Interlaboratory Study Programs are designed to allow customers to validate the quality of the measurements across their network of laboratories driving consistent results in all locations. These programs play an important role in analytical chemistry to assure the quality of measurements. In these studies, DCG provides a group of laboratories aliquots from a homogeneous reference material for analysis. The material is generally a certified reference material, analyzed by methods meeting ISO 17025 and blended by ISO 17034 guidelines and shipped blind to all participating laboratories. After the laboratories analyze the samples, the results are submitted to DCG for consolidation and analysis. DCG will issue a final report to the customer and meet to discuss the results and create an action plan as needed.
Intralaborartory Studies are used to validate the quality measurements of laboratory analysts within a laboratory.

Do you need external analytical expertise?
Specialized Analytical ServicesCONTACT USDCG’s Specialized Analytical Services are provided to customers desiring external analytical expertise.
DCG also offers Specialized Analytical Services. With the analytical capabilities and expertise at DCG, customers often choose to employ Specialty Analytical Services for analyses. Customers utilize this service to supplement customer analytical capabilities and for third party validation. Many customers have found that it is a substantial cost savings to contract DCG to perform all of their analytical services rather than staffing and maintaining their own laboratory or for analyses that are not frequently needed. Prior to any work being done, DCG chemists and technical team meet with the customers, determine the methods that are required meet the requirements and develop a reporting system for the analytical results. DCG has the capability to analyze samples with accuracy and precision following internationally recognized methodologies and to report the results as specified by the customer.
These services include:
- Identification of unknown compounds in the stream that could be causing issues
- Developing “custom calibration” standards based upon the characterized sample
- Providing Analyses to customers desiring avoidance of costly capital expenditures
- Perform Quality Control
- Standard Method Analysis
- Custom Method Development and Analysis
- Act as a third party “tie breaker” in disputes between companies to ensure correct and valid analysis is carried out and accurate reporting is provided
- Confirmation Analysis
